Malcolm-Jamal Warner, the actor, who has died aged 54, was cast as Theo Huxtable in the sitcom The Cosby Show at the age of 13, and over the course of some 200 episodes became one of US television’s best-known teenagers.

The actor, who died last week, carried the burden of representing the meritocratic Black boy par excellence, and made it look easy.

The actor, who died Sunday at 54, was best known for his role as Theo Huxtable, the only son of Cliff and Clair Huxtable, who was based on creator Bill Cosby's son.
